I had a great weekend with M & D in Milledgeville, GA. One of the highlights is seeing this armadillo by the train tracks. Luckily, I had my little video recorder with me:

From wikipedia:

Armadillos are often used in the study of leprosy, since they, along with mangabey monkeys, rabbits and mice (on their footpads), are among the few known non-human animal species that can contract the disease systemically. They are particularly susceptible due to their unusually low body temperature, which is hospitable to the leprosy bacterium, Mycobacterium leprae. (The leprosy bacterium is difficult to culture and armadillos have a body temperature of 93°F, similar to human skin.)

The Nine-banded Armadillo also serves science through its unusual reproductive system, in which four genetically identical quadruplets are born in each litter.[4][5][6] Because they are always genetically identical, the group of four young provides a good subject for scientific, behavioral or medical tests that need consistent biological and genetic makeup in the test subjects. This is the only reliable manifestation of polyembryony in the class mammalia, and only exists within the genus Dasypus and not in all armadillos, as is commonly believed. Other species which display this trait include parasitoid wasps, certain flatworms and various aquatic invertebrates.[5]

Armadillos (mainly Dasypus) make common roadkill due to their habit of jumping to about fender height when startled (such as by an oncoming car). Wildlife enthusiasts are using the northward march of the armadillo as an opportunity to educate others about the animals, which can be a burrowing nuisance to property owners and managers.[4]

Update September 4, 2009When I saw this armadillo, I was thinking of a passage in a book I read recently (I highly recommend it by the way) called Flow: The Psychology of Optimal Experience by Mihaly Csikszentmihaly:

Animals' skills are always matched to concrete demands because their minds, such as they are, only contain information about what is actually present in the environment in relation to their bodily states, as determined by instinct. So a hungry lion only perceives what will help it to find a gazelle, while a sated lion concentrates fully on the warmth of the sun. Its mind does not weigh possibilities unavailable at the moment; it neither imagines pleasant alternatives, nor is it disturbed by fears of failure.

Animals suffer just as we do when their biologically programmed goals are frustrated. They feel the pangs of hunger, pain, and unsatisfied sexual urges. Dogs bred to be friends to man grow distraught when left alone by their masters. But animals other than man are not in a position to be the cause of their own suffering; they are not evolved enough to be able to feel confusion and despair even after all their needs are satisfied. When free of externally induced conflicts, they are in harmony with themselves and experience the seamless concentration that in people we call flow.

The psychic entropy peculiar to the human condition involves seeing more to do than one can actually accomplish and feeling able to accomplish more than what conditions allow. But this becomes possible only if one keeps in mind more than one goal at a time, being aware at the same time of conflicting desires. It can happen only when the mind knows not only what is but also what could be. (p. 228)
